WLAN connections can be frustratingly slow. A German professor wants to put an end to suffering. For the transmission of data, he relies on the speed of light.
In a flash and almost surf without loss of time, which is probably the dream of many netizens. The German Harald Haas, professor of computer science at the University of Edinburgh, is working to make this dream come true. His invention is called “Li-Fi”.
The similarity to the term WiFi does not come from somewhere. 2011 Haas developed the technology that should be up to a hundred times faster than the conventional WLAN, ie the wireless access to the Internet. The trick behind: Li-Fi uses LED lights, which go out and again to send data within nanoseconds through the network. To illustrate: One second has one billion nanoseconds
In this case not only small kilobyte packets are sent – tests showed that the technology brings up to one gigabyte per second to the receiver.. This means that users an HD movie (High Definition) might download in a few seconds. After further tests, the Estonian researchers should have even a speed of up to 224 gigabytes per second measured.
Some airlines are now trying the technology to accommodate aboard their flyer to allow passengers Internet and in the air , “Yahoo! News” reported the CEO of Estonian airline expects that the technology is already used in a few years.
